Abstract (en)
A nozzle plate of a fluid ejection head for a fluid ejection device, a fluid ejection head containing the nozzle plate, and a method for making the fluid ejection head containing the nozzle plate are provided. The nozzle plate contains two or more arrays of nozzle holes (134) therein and a barrier structure (154) disposed on an exposed surface (148) of the nozzle plate between adjacent arrays of nozzle holes (134), wherein the barrier structure (154) deters cross-contamination of fluids between the adjacent arrays of nozzle holes (134).
